REGISTERING DEVICE FOR WATER-METERS.

SPECEFICATIQN forming part of Letters Patent No. 315,786, dated April 14, 1885.

Application filed May 31, 1834. (No model.)

To aZZ whom it may concern:

Be it known that LFREEMAN Wnsron Hoon, of Boston, in the county of Sudolk, of the Comnionwealth of Massachusetts, have invented a new and useful Improvement in Registering Devices for lVaterlieters; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which- Figure l is a side elevation of a meter provided with my invention, the nature of which is definedin the claims hereinafter presented. Fig. 2 is a front elevation, Fig. 3 a side view, and Fig. i a top View, of the main portion, its auxiliary valve and obliquely-slottedstandard, to he described. Fig. 5 is a vertical section of the meter on line a w of Fig. 1, the main piston being shown in elevation, with the ex ception of a portion of it, which is broken away to show the auxiliary valve and its seat. Fig. 6 is a top view, and Fig. 7 a side view, of the ratchet-wheel and its arborfor engaging with the primary arbor of the register. Fig. 8 is a side view of such primary arbor. Fig. 9 is a top view of the operative arm of the ratchetwheel. Fig. 10 is an inner end view of the spindle (1, its duplex earn 0, and slotted disk 6, hereinafter described.

My invention relates specially to the watermeter described in No. 9,37 9 of reissues of United States Patents, dated September 14, 1880. In the drawings, A denotes the meter case or shell, and B the main piston to move rectilinearly within such case. The auxiliary or concave valve of. such piston is shown at C as applied thereto in the ordinary way, except that it is not provided, as represented in such patent, with any rod to extend from it through and slide in the heads of the piston, and being for the purpose of moving the valve first in one and next in the opposite direction by being carried against the heads of the shell or case alternately.

In practice it is found that leakage is apt to take place through the holes in which the said rod slides, and therefore I, to avoid such leakage, adapt other and different means of operating the valve and regulating the extent of its movement as may be required to cause the met-er to correctly indicate the amount of water delivered through it.

Although I have herein described, and in the drawings represented, means of regulating the extent of movement of the valve, they are not herein claimed, they being shown and claimed in my application for a patent numbered 150,599, filed December 9, 1884. The valve 0 is provided at its middle with an extension, a, in which is a rectangular recess, 12, within which there extends a duplex cam, formed as shown at c, in end view in Fig. 10.

- The device 0, for convenience termed a duplex cam, does not in its use perform the functions of a cam, but rather that of a stop, as hereinafter explained. This cam is situated at the inner end ofa short spindle, d, that extends from a slotted disk, 6, and turns in a cylindrical hole or bearing, 1', arranged in the shell at the middle and at one side thereof. The disk has two areal slots, f, made through it concentrically with the axis of the spindle, and such disk rests against the circular face of a cylindrical projection, 9, extended, as represented, from the shell. Heading-screws h h go through the said slots and screw into the projection g, and answer to clamp the disk thereto. By turning the disk so as to revolve the spindle on its axis more or less the duplex cam will be correspondingly turn ed within the recess 1). This cam, with the ends of the said recess, serves as stops or means to arrest the valve in its reciprocating movements, and to determine the extent of each of such movements, each being increased as the obliquity of the cam to the recess is increased, and diminished as such obliquity is diminished by turning the disk. Leakage through the hole z'is easily prevented by a washer, 7c, encompassing the spindle between the disk and the projection g, toward which latter the disk is to he forced by the screws h. The spindle d is tubular and has within and projecting from its bore a slide, 1., and in rear thereof a spiral spring, it, against which the slide bears when also bearing against the auxiliary valve. This slide and spring are to allow the said valve to give way or move backward in case of any 0bstruction getting between it and its seat and operating to prevent the valve from properly working.

Having thus described a means of regulating the extent of movement of the valve 0, as

provement or invention, which is a combination applied to the meter case or shell and to its main-piston and the primary arbor of the register for the purpose of revolving such ar bor.

It further consists in having to the metercase and the said combination of mechanism a hood extending from and opening out of the upper head of such case, all being essentially as explained.

To the upper end or head of the piston B a standard, E, having within it an oblique slot, Z, is fastened. Into this slot an arm, F, at its outer end enters. This arm turns on the upright spindle m of a ratchet-wheel, G, and carries a pawl, n, to engage with such ratchetwheel. The spindle m goes upward through the upper head, 1, of the shell or case, and turns in a stufling-box, t, applied thereto. At its upper part the spindle is tubular, while at its upper end it is grooved diametrically, as shown at 0. The primary or main arbor p of the register H extends at its foot into the bore of the spindle m, and is provided with a pin, q, to enter the groove 0, the said pin going dia-. metrically through the arbor. The groove and pin serve to so engage the arbor and spindle as to cause the former to be revolved with and by the latter in its intermittent rotary movement.

From the above it will be seen that the described mode of applying the said primary arbor to the spindle admits of the two being readily disengaged when it may be desirable to remove the register from the shell, or of being as easily engaged when the register is in the act of being adapted to the shell. The cover or head 7" of the shell is provided with a water-tight hood or chambered projection, s, to

extend upward from it, as shown, and to open through the head and receive thestandard E as the piston may rise to its highest position.

As the piston may move upward and downward within the shell, there will be imparted to the arm F reciprocating movements,whereby its pawl will be made to turn the-ratchetwheel, and thereby produce a corresponding rotary movement of the primary arbor p.

I do not claim the water-meter described in the said Patent No. 9,379 of reissues of United shell, the main piston thereof, and the primary arbor of the regulator, of mechanism, substan tially as described, consisting of the slotted standard, (projected from the pistonhead or upper end,) the ratchet-wheel and its tubular and grooved spindle, (applied to the head of the case,) and the arm and its pawl, such arm being revoluble on the said spindle and extended into the slot of the standard, and all being arranged and to operate essentially as specified.

2. The meter case or shell provided with the hood extending from and opening through its upper head, in combination with the slotted standard projecting from the main piston, and with the ratchet=wheel and its spindle, and

with the actuating-arm extended intothe said standard and provided with a pawl, and arranged,.as described, with the ratchet-wheel, all being substantially and to operateas set forth.
